Meridian Peak (5,978ft) is small peak in North Salt Lake along the Bonneville Shoreline Trail and just north of Ensign Peak. The main trail also takes you past Matt's Arch (aka "Industrial Arch") - a tiny natural arch made of limestone.
Paul Bunyan's Woodpile is an interesting geological feature in Central Utah, that looks like a "woodpile" of logs left behind by the giant lumberjack of American & Canadian Folklore. Really the woodpile is a cluster of lava rocks formed about 30 million years ago; the logs were then formed into orderly columns.
